"Cleaning Reimbursement" to seller's agent...

So I bought a condo about a month and a half ago...something has been bothering me though.

The seller's agent somehow snuck in a $200 "cleaning reimbursement" on the HUD document that I don't recall ever agreeing to. I didn't notice it until after closing.

When I moved in, the floor was super grimy. The toilet had been used and was not flushed and stunk up the whole bathroom. It was definitely not "cleaned" since the time of my tour and closing, just the staging furniture was removed.

I realize $200 is not much compared to the rest of the closing costs, but I find it pretty unethical to be charged for a "cleaning" that clearly never took place.

I tried to do a search on "cleaning reimbursement" fees and couldn't find anything, which leads me to believe this is just a BS charge so the seller's agent could pocket an extra couple hundred bucks or so.

How would you handle this situation? I know it's tempting to say "let it go" but unless I can determine this charge is totally standard (which I don't believe it is) I'm not the type of person to let something like this go, regardless of amount.

Any advice would be appreciated.
